SLIDE BUCKLE Patented May 3, 1932 'l` @FSFECE JOHN H. DOMKEE, OF WEST HAVEN, CONNECTICUT, ASSIGNOR T0 THE WIRE NOVELTY lVIANUFACT'URING COMPANY, OF WEST HAVEN, CONNECTICUT, A CORPORATION 0F CONNECTICUT SLIDE BUCKLE Application filed August 1, 1931. Serial No. 554,439.

rl`his invention relates to that class of buckles known as slide buckles employed for adjusting the length of looped straps, webbing and the like, upon which the buckle is mounted, the adjustment being maintained thereby without any penetration into the material. The invention about to be disclosed is an improvement upon the device described and illustrated by your petitioner in two applications for Letters Patent, filed July 16, 1931, Serial Numbers 551,116, and 551,118, respectively, the first application disclosinga single piece of wire structure bent to provide a pair of loops in a common plane, the loops being separated by intermediate bars angularly bent along the plane of the loops, engaging metals of the free sides of the loops and the bar extremities, engaging a side structure, each being united as thus engaged in permanent intimate union, and the second application disclosing substantially rectangular units of which a pair is associated in a common plane and certain engaging metal surfaces of the pair of units, thus arranged, being united in permanent intimate union to provide a slide buckle having intermediate bars angularly bent along the plane of the units. In the device herein disclosed, however, the structure differs from either of the structures previously disclosed in that, while the buckle frame is of substantially rectangular form, the intermediate bar structure is formed from a separate piece of wire and se cured and maintained within the plane of the frame by means of uniting in permanent intimate union the engaging metals of both extremities of the intermediate bar structure with a side structure. The objects of the invention, therefore, are to provide a substantially rectangular buckle frame with an inter mediate bar member wholly lying and secured to the frame within the buckle plane; to provide such a frame with an intermediate bar structure of which both extremities engage a side structure of the frame and the engaging metals united in permanent intimate union; and to provide substantially rectangular buckle frame from a piece of wire the ends of which abut within a side struc ture, and an intermediate bar structure of which both extremities engage a side structure of the frame, the metals, thus engaging within and at the side structures, being united in permanent intimate union. With these and other objects in view as may become apparent from the within disclosures, the invention consists not only of the particular form herein pointed out and illustrated in the drawings, but readily admits of certain modification within the scope of what hereinafter may be claimed.

The character of the invention may be best understood by reference to one illustrative device embodying the invention and illustrated by the accompanying drawings in which the Figure 1 is an upright elevation of the device; and the Figure 2 is an upright side elevation thereof; the Figures 3 and 4C each being a modified form of the device.

Referring more particularly to the drawings, the improved slide buckle is made in two parts of which each part is made from a separate piece of wire or other desired material. VThe frame 1 is preferably made of wire bent in substantially rectangular form having upper and lower horizontal bars 2V and 3, respectively, and side structures i and 5 so that the wire ends 6 and 7 are made to abut in the formation of one of the side structures as in the middle of the side structure 4. The intermediateV bar structure 8 is preferably made by bending a piece of wire in the middle and thenvback upon itself to provide the associated bars 9 and 10 having` the free extremities 12 and 13 and the looped extremity 14, each of these bars being provided with a series of angular bends extending in a common plane in opposite directions to provide the projections 11.v The intermediate bar structure 8 is placed within the buckle frame 1 so that it will lie flat within the buckle plane and each of its extremities 12-13 and 1li will engage a middle of a side structure. rlhe parts 1 and 8 thus associated may be relatively secured, together with the abutting wire ends 6 and 7, in any desired manner, but it is preferred that the engaging metals of the'looped extremity 14 andthe side structure 5 be united in permanent inti-V mate union, as by welding, brazing or soldercluding all structural connections, lie Within a common plane, the structure therefore being reversible in that an upright elevation, reverse to that illustrated by the Figure 1, is substantially identical therewith, and the structure being indestructible in that theY union of the engaging metals is so permanent that the original character of the metal surfaces cannot be restored by any means effecting'the mere separation of the parts.

The Figures 3 and 4 illustrate modifications of the preferred form of the device and differ therefrom only in that in the Figure 3 the intermediate bar structure 8A extends straight across the buckle frame 1A Wit-hout projections; and in that in the Figure 4: the intermediate bar structure 8B is a single bar also extending across the buckle frame 1B. In both instances the modified forms of slide buckle parts are made reversible and indestructible as in the. preferred form by means of uniting the structural connections and parts in permanent intimate union, as aforesaid with regard to the preferred form of' the device.

1. A slidebuckle comprising a substantially rectangular frame having upper, lower and side structures, and a separate intermediate bar structure having extremities each secured in permanent intimate union, Within the plane of the frame, to an inner surface of i a side structure, the intermediate bar structure lying Wholly Within said plane.

2. A slide buckle comprising a substantially rectangular frame having upper, lower and side structures, and a separate intermediate bar structure having extremities, each engaging, Within the plane of the frame, an inner surface of a side structure, the intermediate bar structure lying Wholly Within saidvplane, and the engaging metals of said extremities and said side structures being united in permanent intimate union.

3. A slide buckle comprising a substantially rectangular wire frame having in one common plane upper, lower and side structures, the Wire ends abutting in a side structure, and an intermediate bar structure placed Within the frame and having extremities the metal surfaces of which are united in permanent intimate union with the met-al surfaces ofvtheir adjacent side-structures, the
